Otherworlds
What are the otherworlds in Buffalo Woman Shamanism?
They are all other worlds that are not what we understand as the material world, the everyday world, or everyday life.

The other worlds comprise all spiritual realms. It is the afterlife, which, like this world, is (only another) reality. A different reality, however, that does not contradict this world but is in connection and exchange with it.

As a transcendent being, Viola, as the white buffalo woman, is a conscious part of these other worlds/the otherworld.
